一种火箭助飞鱼雷攻潜末弹道被动定位方法

摘要

为了有效测量火箭助飞鱼雷攻击潜艇的末弹道轨迹,文中提出了一种基于艇载舷侧阵的被动定位方法,介绍了测量系统的组成和功能,提出了目标的被动定位算法,并在测量区域内对误差进行仿真,得到绝对误差和相对误差分布图.仿真结果表明,在测角误差最大为0.3°的条件下,采用该方法,在艇正横±60°,距离目标65 m区域内,能达到1％斜距的测量精度.文中研究可为末弹道被动测量系统的总体设计及测量数据处理提供参考.%To effectively measure the terminal trajectory of a rocket-assisted torpedo attacking submarine,a passive positioning method based on the broadside array of submarine is presented.The composition and function of the measurement system are introduced,the target passive positioning algorithm is proposed,and the error in the measurement area is simulate to obtain the absolute and relative errors distribution map.Simulation shows that under the maximum angle measurement error of 0.3°,the measuring accuracy reaches 1％ oblique distance in the range of submarine transverse angle ± 60° and in the area of target distance 65 m.This method may provide a reference for the overall design and measurement data processing of the passive terminal trajectory measurement system.
